To (all whom is may concern:

Be it known th t LCHAsLEs K. PrcKLEs, a citizen of the United States,and a resident ofthe ciiy of Philadelphia, county of Philadelphia, andState of Pczmsylvsnls, have invented new and. useful lmprovement inBrslrelisngers, of which the following is a specifics/bros.

The object of my invention is to improve articles of this class, so thatall adjustments rrecosssry to compensate for weer will he sutomatlcellytaken up, wheres the hanger will require no attention end Will neverchat or rattle. This object is accomplished by my icvsntiorr, oernembodiments cl which are heroine For 2?, more pm tricolor 1 descriptionof my isventioo refereocsls to be had to the accomforming e part-hereof,m wtuch is s sectional View showing my s is place.

I Fig. 5.

e'sosset 2 comprises s vertical web 9,

The Web 9 is by bolts 15 shots recessed st;

ployerl, it is better to unite the segments by an annulus 22,

In any case the hanger 3 is made so that the balls 18 are s rung sportbecause of the resilient nature or the shank 17, :w th' the sockets 2and 4 are always fitted by these I halls 18 at the proper tension, sothat st ell l tunes the compensstlons for ear sre escorotely made.

The heaol 5 is provided with vertical webs 23 and a horizontal web 24,which is bolted to'the beam 7 by means of bolts 25, which also hold thepiece 6 in place.

When the elements are assembled, the ports of the'balls 18 arepreferably clamped together or nearly together by suitable removableclamps on. the shank 17. position in their sockets, these clamps areremoved and the hanger S'then automatically assumes its proper positionabove described,

If s more positive action of the hangers is desired, it may be had byone of the means shown in Figs. 7 to 10; inclusive.

In Figs. 10 and 8 the segments are seporated by springs. Coiled springsin recesses 31 are shown in Fig. 10 and leafsprings 32 in recesses 33 inF 1g. 8.

In Figs. 7 and 9 the parts 19 sud 20 are provided with cams 3.4, a wedge35, e spindle 36, extendingexlally therefrom, a spr1ng37, surroundingsaid spindle, and s In 38 on the part 19, through which the splnd cextends. A not or nuts 39 limit the movement of the wedge and theseparation of the parts 19 and 20 under the action of the-spring 37. InFigs. 7 and Q the wed es and. cams'are shown in opposite directlonghutas the functions are identlcsl'in either case one description onswersfor both.

In Figs. 7 to 10 only one cool of the hunger is shown, the other beingidentical, so further clescriptiou is unnecessary.

Another form of automatic brake-hanger is shown Fig 11. In thisembodiment the hanger 420 is preferably s lit throughout its entire logth except st t ecenter whereby the spri ot-infill 42, 43, and 4A areformed. The srm 41 has a conical hoped st-u 1 45, which issuitfllofifitect 11 thetrucl l rame. This stud is'slso provfclcd'with acylindrical port 46, which fits shore in the arm 42. A washer 47 andcotts; hold 7 these psrts togfifi hetg.

as indicated by dotted lines on When in erforation which readilyunderstood.

This structure may be applied to each end of E the hanger, althoughpreferably I employ j arms 43 and 4-4, which are substantially identicalwith the arm 41, and the pin 49 is provided with the integral cone 50and the nonrotatably-mounted cone 5],which is held in l lace by a nut 52in the usual way. In this orm of my invention the wear is automa'ticallytaken up by the coned arms rising on the cones under the spring actionof the arms.

Yet another form of my invention is found disclosed in Fig. 12, in whichthe hanger 60 is substantially U-shaped, its central upper portion 61being depressed. The arms 62 of this hanger-60 are slightly enlarged andprovided with conical bores which are ada ted to receivesimilarly-shaped and rigid ugs on the brake-beam orhanger. Thetruck-frame is provided with jaws 63 and 64, one of which-is adjustablymounted with regard to the other, and they are brought together andagainst the hanger 60 by means of a bolt 65. The recess in which thehanger 60 rests is so shaped as to permit a slight turning movement.- Bytightening the bolt 65 the part 61 of the Y hanger 60 is somewhatstraightened, thereby 1 causing the free ends of the arms 62 to be ibrought together, whereby any wear may be readily taken up with oneadjustment.

From the foregoing myinvention will be I do not, however, regard itrestricted to the precise features herein described, as it may be variedin many details without change of substance. I regard its scope asdefined by the annexed claims,

What I claim is- 1. In a device of the'class described, a socket, fixedto a t-ru :k-frame, a socket secured to the brake beam or head, and ahanger having'resilient ends which fit said.

sockets.

2. In a device of the class described, a socket secured to atruck-frame, a socket secured to a brake beam or head, and hanger havingresilient ball-heads fitting in said sockets.

3. In a device of the class described, a socket secured to atruck-frame, a socket secured to a brake beam or head, and a hangerformed ol two resilient parts with enlarged I'heads fitting saidsockets, and means for holding said parts together.

4. In a device of the class described, a socket secured to atruck-frame, a second socket formed in a brake-head and a piece securedto a brake-beam and a hanger with enlarged endsresting in said sockets.

5. In a device of the class described. a brake-hanger -.oni rising ashank with'di-- Vided heads, and springs for causing a separation oi"said heads.

6. In a device of the class described, a brake-hanger comprising a shankwith a divided head, cams, and a spring-actuated wedge for separatingthe parts of said head.
